hey guys, just asking for the experts here to give me a hand..ive designed an LM3886 amplifier of my own, BUT im not sure what wvales to use..the schematic is given below..any help would be much appreciated

First I made a mistake, L1 should be .7mh dont know what I was thinking when I typed 7.4???? Just wind 10 turns of .4 enamel wire on the body of the 10 ohn 2watt resistor.
The mute pin needs 20ma at V- to shut off the mute feature. When the pin is open mute is active.

yes i understood that bit by reading the datasheet..the reason i have the Mosfet in there is because im making a preamp which is microcontroller controlled...therefore i can have input select and mute options...is this feasable?
